生态学
; 淡水 底中水层性; pH range: 6.0 - 6.5; dH range: 5 - 12. 熱帶; 22°C - 26°C (Ref. 1672); 8°N - 6°N
Asia: restricted to forest streams from the Kelani to Nilwala basins in Sri Lanka. It occurs in hilly areas up to about 300 m elevation. The brightly colored population introduced to Mahaweli at Ginigathena, Sri Lanka are said to have diminished in number due to the aquarium export trade.
亞洲: 侷限於在斯里蘭卡森林溪流從 Kelani 到 Nilwala 流域了。 它出現於中多丘陵的區域達到大約 300 公尺海拔。 色彩鮮豔的族群引進了在 Ginigathena 的 Mahaweli, 斯里蘭卡據說已經數量減少由於水族館輸出貿易。

Inhabits clear, cool, shady streams in forested areas, on gravel or sand substrate. Sometimes found in pools of quiet water in the margins of clear streams and rivers (Ref. 6471). Bred in captivity. Spawns in shallow water among marginal weeds. Eggs (>100) hatch in 1-2 days; fry are free-swimming after 24 h (Ref. 6702). Feeds mainly on filamentous algae and detritus (Ref. 6703). Males brightly colored and with darker fins. Popular aquarium fish. Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 80 cm (Ref. 51539).
在砾石或沙子底部上, 在森林区域中栖息于清澈寒冷又暗的溪流。 有时在清澈溪流与河的边缘中发现于静止的水域的水池。 (参考文献 6471) 在繁殖场中饲养了。 产卵在杂草丛之中的浅水区。 卵 (>100) 在 1-2 数天中孵化; 鱼苗在 24 h 之后是游离于水中。 (参考文献 6702) 主要吃菌丝藻与碎屑。 (参考文献 6703) 雄性色彩鲜艳的而且有较深色的鳍。 受欢迎的水族馆鱼。 水族馆保持: 形成 5个或更多个体的群体; 水族馆最小体型 80 公分.(参考文献 51539)
